Can a Customer Number be used for multiple patent applications?

Yes, a Customer Number can be used for multiple patent applications. This is one of the primary benefits of the Customer Number system. The MPEP 403 states:

‘The Customer Number practice permits applicants, attorneys, and agents of record to change their correspondence address for a number of applications with one request.’

This means that:

• A single Customer Number can be associated with multiple patent applications
• Changes to the correspondence address or list of registered practitioners can be made once and applied to all linked applications
• It simplifies portfolio management for applicants and law firms handling multiple patents

Using a Customer Number for multiple applications streamlines communication with the USPTO and helps ensure consistent handling of related patent matters.
